NAME

       pmLookupText - return text describing a performance metric

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmLookupText(pmID pmid, int level, char **buffer);

       cc ... -lpcp

DESCRIPTION

       Retrieve descriptive text about the performance metric identified by pmid.

       The  argument  level  should  be   either  PM_TEXT_ONELINE  for  a  one-line summary, else
       PM_TEXT_HELP for a more verbose description, suited to a help dialog.

       The space pointed to by buffer will have been allocated in  pmLookupText  with  malloc(3),
       and  it  is  the  responsibility  of  the caller to free(3) the space when it is no longer
       required.

       pmLookupText returns zero on success.

DIAGNOSTICS

       PM_ERR_NOTHOST
              For archives created with versions of PCP  prior  to  4.0,  if  the  current  PMAPI
              context  is an archive log (help and one-line text was previously not maintained in
              the archive logs)
